I wish I could say I made this from scratch, but that would only be a half truth. The cake is from a box with pudding in the recipe, very moist. The icing is adapted from a recipe in a, appropriately named, cupcake recipe book.
The recipe is for Creamy Chocolate frosting and is in “Betty Crocker: The Big Book of Cupcakes” ISBN 978-0-470-90672-9
